Tharabar Gate is the main gateway to the ancient Bagan city. It is the eastern gate of the old wall. It is now the only structure left of the old city built by King Pyinbya. It was built in 849 A.D during the 9th century. The western and northern part of the city wall were washed away by the river. There was originally twelve gates during that time. Tharabar is derived from the Pali term "Sarabhanga" meaning "shielded against arrows".

Although most of the structure is ruined. stucco carvings of the ogres can still be found. The gate is known to be guarded by spiritual beings. On the left is the side of the gate is the brother "Lord of the Great Mountain" and on the right side is the sister "Golden face".
